COMBINED COOKING AND HEATING STOVE OR RANGE.

To all whom t may concern:

Be it known that we, JOI-IN C. GALLA- GHER and HUGH P. GARVEY, both citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Combined Cooking and Heating Stoves or Ranges, of which the following is a specification.

llhis invention relates to a stove or range adapted for both cooking and house heating purposes, or which may be employed solely as a heater, as desired.

The object of the invention is to provide a combination heating and cooking stove or range embodying improved means for heatw poses, and improved means for effectually utilizing the heat for either cooking or house warming, and directing the course of the products of combustion for either purpose so as to utilize all the available heatunits of the fuel.

A further object of the invention is to provide a construction of heating means which may be employed with beneficial results in hot water or hot air furnaces.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a sectional plan view of a stove or range embodying the invention. Fig. 2 is a vertical section on line. 22 of Fig. 1. Fig. 3 is a rear elevation of the stove with the rear casing partially broken away. Fig. 4 is a horizontal section on line 4 4 of Fig. 3. Fig. 5 is a vertical section on line 5 5 of Fig. 1. Fig. 6 is a vertical section showing a modification. Fig. 7 is a section on line 7 7 of Fig. 6.

Referring to the drawings, 1 designates the body of a cooking and heating stove or range, to which the invention is shown applied in the present instance; 2, the oven; 3, the lire-box; 4, the grate; 5, the ash-pit; 6, the horizontal combustion space above the oven; 7, the Hue or passage connecting the same with the top of the fire-box; 8, t-he down draft flue between one of the side Specification of Letters Patent.

walls of the body and the outer side wall 9 of the oven; 10, the heat circulating space between the oven and bottom of the body divided by the diagonal partition 11 into inlet and discharge portions 12 and 13 in communication through a passage 14; 15, an outlet or draft opening in the rear wall of the body and communicating with said portion 13 of the space 10; and 16, 17, 1S and 19, the oven, fire-box, ash-pit and clean-out doors. The construction thus far described may be that common to ordinary cooking stoves or ranges, modified in arrangement according to the principle of the present invention, as hereinafter described.

Arranged between theinner sides of the lire-box and oven and spaced from the latter is a heating chamber 20, shown in Figs. 1 to 5, inclusive, in the nature of a water back, one side of which is lined by the usual fire-brick or clay and forms the inner side wall of the fire-box. The space 21 between this chamber and the oven provides a vertical flue co-eXtensive in depth with the fire-box, said flue being closed at its base and top and having at its rear a draft opening or outlet 22 formed in the back wall of the body. rPhe flue also communicates at the front with the fire-box through lateral ports 23. A similar heating chamber 24, also shown in Figs. 1 to 5, inclusive, in the form of a water baclr may be arranged between the outer side of the fire-box and adacent side of the body and spaced from the latter to provide a vertical flue 25. This chamber 24, together with the fire-brick lin ing, may serve, as shown, as the outer wall of the fire-boX, and the flue 25, like the flue 21, is closed at its base and top and communicates with the front of the fire-box through a vertical series of lateral ports 26. At its rear the flue 25 is provided with a draft opening or outlet 27 formed in the back wall of the body. Connecting with the heating chambers or water backs are water inlet and discharge pipes 28 and 29, forming part of a circulating system, whereby the water heated in said chambers may be circulated for culinary or heating purposes. It will be apparent that when the draft outlets 22 and 27 are open all the smoke and gases will flow into the ues through the lateral ports 23 and 26 and thence travel rearwardly to the discharge outlets, whereby the large proportion of the heat units will be utilized to heat the chamber. The water passing through the water'backs will accordingly be rapidly and highly heated, allowing a large quantity to be circulated for culinary or heating purposes.

Disposed upon the back of the body is a smoke chamber or casing 28 provided with the usual collar 29 for connection with the smoke pipe 30, through which the products of combustion finally discharge to the atmosphere. Arranged in said chamber or Vcasing are dampers 31, 32 and r33, controlling t-he vrespective outlets 15', 22 and 27. The dampers 32 and 33 are connected with a sliding operating rod 34 extending at its outer end to the exterior and provided with a knob 35 for manual actuation, while the damper 31 is carried by a pivoted lever 36. When the rod is drawn outward, the dam pers 32 and 33 willv be closed to cut olf the flow of the gases through thev flues 21 and 25, vwhile the damper 31 will be opened to allowY all the heat and gases to circulate around the oven. When, on the other hand, the rod is pushed inward, the dampers 32 and 33 will be opened for the passage of the heat and gases through the Hues 21 and 25, while the damper 31 will be closed to cut orf the flow of heat and gases from about the oven. Vhen the oven is not in use, therefore, the full amount of heat generated may be utilized to heat the contents Vof the chambers 20 and 24. Y

Within the broad aspect of the invention within the terms of the appended claims, the

Voven constitutes a heating space or'chamber,

as will be readily understood. VThe chambers 20-and 24 may serve to heat water or air and may be in the form of shells, as

Vshown in Figs. 1 to 5, inclusive, or they may each be formed of spaced plates 37 and 38 and' contain a water or air heating coil 39, as shown in Figs. 6 and 7 in which event theY terminals of the coil will connect with the pipes'28 and 29 and the inner'plate may be provided with an asbestos lining 40. In the construction shown in Figs. 6 and 7, as will be readily understood, the space between the plates forms the flue, the coil itself constituting the chamber. It will be observed that the coil is ofsuch form as to permit 'V ready passage of the gases around the coil through the space betweensaid coil and the walls of the flue, and also longitudinally i through the spacel bounded by the convolutions of the coil and laterally through the spacesrbetween the convolutions ofthecoil,

whereby all of the convolutions will be enveloped by the smoke and gases and the contents thereof rapidly heated.
